Alfa Laval valve indication units provide basic information about the position of valves used in hygienic applications. Based on proven technology, this range of valve position indicators offers safe, reliable and economical operation.

Safe, reliable and economical indication

Alfa Laval indication units are cost-effective digital devices with up to two feedback signals that are mounted directly on the valve yoke, which provide feedback on the valve’s open/closed position. These valve position indicators (Side indicator and brackets) may be used on any Alfa Laval valve, but are especially competitive solutions for Alfa Laval SSV Single seat valves,and mixproof valves (brackets), and butterfly valves.
Four types of valve indications

Alfa Laval offers these standard valve position indicators for hygienic industries:
Inductive proximity sensor

Based on principles of electromagnetic conductivity and metallic detection, this non-contact electronic sensor is inherently resistant to dust, humidity and oil in industrial environments. This increases operational safety and reliability.
Hall proximity sensor

Based on principles of electromagnetic conductivity and magnetic detection, this non-contact electronic sensor provides safe and accurate detection of valve position compared to conventional proximity sensors. It provides enhanced reliability and longer service life for valve position sensing in any operating environment.
